Aloris Indexable Carbide Insert Boring Bar CBB-50

The Aloris CBB-50 is a premium Indexable Carbide Insert Boring Bar engineered for precision and durability in both manual and CNC lathe operations. Constructed from alloy steel and heat-treated for superior rigidity, the CBB-50 ensures minimal deflection and maximum tool life during demanding boring tasks.

This versatile bar accepts popular triangular positive rake inserts, which are held firmly in place using a flat head screw, ensuring consistent insert orientation and cutting accuracy. Ideal for through-hole boring, precision facing, or boring to square shoulders, the CBB-50 is also compatible with boring heads and can access minimum bore diameters as small as 7/16″.

To match specific setup requirements, the bar can be cut to length using an abrasive cutoff wheel without compromising performance. Whether you’re working in a high-speed CNC environment or on a manual lathe, the CBB-50 offers unmatched performance, versatility, and repeatability.
